Until officials identify a culprit and motive in the Boston bombing, the Left should calm down.

At this writing, no one knows who planted two bombs in Boston that killed three people, wounded 176 others, and forced doctors to amputate the limbs of at least 13 maimed victims. Authorities have yet to arrest the murderer(s), whose motivations remain mysterious. (While the FBI released photos of two possible suspects late Thursday, their names and backgrounds are not evident.)

(UPDATE: As of 11:00 a.m. on Friday, April 19, alleged bomber Tamerlan Tsarnaev, 26, died at 1:35 a.m. after a shootout with police. His 19-year-old brother, Dzhokhar A. Tsarnaev, remains the focus of an intense manhunt. The self-identified Muslim is considered armed and extremely dangerous. On Facebook’s Russian language page, he describes his worldview as “Islam.” The Tsarnaev brothers reportedly came to America 10 years ago from Chechnya, a Russian-province torn by anti-Moscow, separatist violence fueled by radical Islam. An online photo gallery called “Will Box for Passport” says this about the deceased brother: “Tamerlan says he doesn’t drink or smoke anymore: ‘God said no alcohol. A muslim [sic], he says: ‘There are no values anymore,’ and worries that ‘people can’t control themselves.’” Tamerlan also once said: “I don’t have a single American friend. I don’t understand them.”)

Nonetheless, while investigators labor valiantly amid such uncertainty, omniscient liberals already have concluded who unleashed this carnage: the far Right.

“We really don’t know who did this,” Obama strategist David Axelrod told MSNBC. “It was Tax Day.” Presumably, the bombs were meant to hammer high tax rates rather than pressure the much-maligned 1 percent to pay “their fair share.”

CNN’s Peter Bergen explained that if the bombs contained conventional explosives — instead of al-Qaeda’s favorite, hydrogen peroxide — the attackers “might be some other kind of right-wing extremists.” According to CNN’s Tim Lister and Paul Cruickshank, “a senior U.S. counterterrorism investigator told CNN that pressure cooker bombs have also been a signature of extreme right-wing individuals in the United States who he said tend to revel in building homemade bombs.”

The Huffington Post’s Nida Kahncommented, “We don’t know anything yet of course, but it is tax day & my first thought was all these anti-gov groups.”

MSNBC’s Chris Matthews declared, “Normally, domestic terrorists, people tend to be on the far right.”

Really?

Yes, overzealous pro-lifers justifiably have been jailed for attacking abortion clinics. And truck bomber Timothy McVeigh considered Thomas Jefferson a guiding light, which some on the Left may believe places McVeigh on the right. But McVeigh, who was executed in June 2001, also seemed driven to avenge Iraqi civilians killed by America’s armed forces. As he wrote, “When you approve, morally, of the bombing of foreign targets by the U.S. military, you are approving of acts morally equivalent to the bombing in Oklahoma City.”

Matthews must have forgotten the three Occupy Cleveland activists and two others arrested last April for conspiring to bomb an Ohio bridge. According to an FBI affidavit, these liberal extremists wanted everyone to know “that the action was against corporate America and the financial system, and not just some random acts.”

Occupy Wall Street activists have committed arson and vandalism and even been caught with homemade hand grenades.

One Cape Cod mansion under construction succumbed to arson in November 2010, and another manor was targeted eight days later; it survived when an incendiary device failed. Both properties were graffitied with the words “F**k the rich” — hardly a conservative battle cry.

In August 2003, Earth Liberation Front eco-terrorists in California torched a Hummer dealership and a housing complex. ELF posted a banner that read, “If you build it, we will burn it.” ELF firebugs inflicted $12 million in damage to a ski resort in Vail, Colo., in 1998.

By pinning Boston’s bombs on the Right, the Left may humiliate themselves yet again. They did so after Jared Lee Loughner opened fire in January 2011, badly injuring former congresswoman Gabrielle Giffords (D., Ariz.) and twelve others, and killing six more.

“Violent acts are what happen when you create a climate of hate,” columnist Paul Krugman scrawled. “And it’s past time for the GOP’s leaders to take a stand against the hate-mongers.”

“If Sarah Palin . . . does not repudiate her own part in amplifying violence and violent imagery in politics,” MSNBC’s then-host Keith Olbermann thundered, “she must be dismissed from politics.”

Krugman, Olbermann, and other Lefties looked idiotic when Loughner proved to be not a libertarian but a lunatic.

“What do Chocolate cookies taste like?” Loughner wondered online. Elsewhere he posited: “The government is implying mind control and brainwash on the people by controlling grammar.”

The person(s) behind Boston’s carnage may want steep tax cuts, strict cap-and-trade regulations, or sharia law. Perhaps the problem is plain, old-fashioned mental illness. As of Thursday afternoon, no one from Obama to FBI director Robert Mueller to Governor Deval Patrick (D., Mass.) knows who bombed Boylston Street. Until officials identify a culprit and motive, left-wing loudmouths should seal their lips.

UPDATE: As of 9:30 a.m. on Friday, April 19, alleged bomber Tamerlan Tsarnaev, 26, died at 1:35 a.m. after a shootout with police. His 19-year-old brother, Dzhokhar A. Tsarnaev, remains the focus of an intense manhunt. The self-identified Muslim is considered armed and extremely dangerous.

I don’t understand them.”
